In dogs, during natural mating, occurs the projection of a considerable portion of the ejaculate into the uterus, through the cervical canal, during the coital tie (England et al., 2006; Thomassen & Farstad, 2009). Semen collection in the dog is a relatively easy procedure, although requiring some training for optimization of the technique. Surgical insemination technique have been proposed once for frozen semen or when the bitch presents an anatomical obstruction that prevents the insertion of the catheter or endoscope. In Artificial Insemination (AI) the semen is collected manually from a stud male and thereafter deposited (inseminated) in the female so that fertilization can occur in the absence of natural mating.

For laboratory values, the serum progesterone is typically less than one ng/ml until 2 days before ovulation. This thickens the lining of the uterus to prepare for pregnancy. The bitch should be muzzled and firmly restrained. A small drop of about 20 L of semen is placed on in a pre-warmed slide and cover by the coverslip. Before offering canine AI services, practitioners ought to specialised themselves, acquiring profound knowledge of the reproductive physiology and pathology of the species and the skills to collect semen and to inseminate the female without risking animal health or welfare. AI becomes unnecessary when there is a good genetic diversity (unrelated individuals) living within easy travelling distance of each other. To ensure that ethical issues are minimised, FCI recommends that AI should only be done in healthy dogs with proven fertility (article number 13). The observation of the cranial part of the vagina is performed for this purpose. Proestrus lasts roughly 9days during which your dog will typically be bleeding.

It results in the collapse of vaginal folds. According to this study, the tested semi-quantitative assay estimated higher progesterone concentration than. Other methods has been proposed to monitor the bitch oestrous cycle, such as serial reading of the electrical resistance of the vaginal mucus around the time of ovulation, using probes inserted into the vagina during the heat period (Fontbonne, 2008), or the crystallization patterns in anterior vaginal fluids (England & Allen, 1989) or in saliva (Pardo-Carmona et al., 2010), which have been found up not to present an acceptable reliabily in the identification of the canine ovulation.

Tumors are usually diagnosed with an examination by a vet along with bloodwork. Artificial insemination is a noninvasive procedure that places sperm directly into the cervix or uterus, increasing the odds of pregnancy. However, despite the influence of the intrauterine vs. vaginal insemination on the success of the procedure, once intrauterine insemination is achieve, the exact place of semen deposition is not of the main importance for the sperm distribution within the uterus (England et al., 2006; Rijsselaere et al., 2004). Making matters more confusing, some dogs have silent heats meaning little or no obvious signs of heat such as swelling or bleeding.
